Folks,
I'm the author of an IETF Internet Draft that discusses a problem arising
from the current TCP's reaction to soft errors. The problem has to do with
long delays in connection establishment attempts that may arise in a number
of scenarios.
The draft proposes to change TCP's reaction to soft errors so that
connections that are in the SYN-SENT or SYN-RECEIVED states are aborted
upon receipt of an ICMP error message that indicates a soft error.
The draft can be found at:
http://www.ietf.org/internet-drafts/draft-gont-tcpm-tcp-soft-errors-00.txt .
I've also put online a "Discussion List" I had prepared for the last IETF
meeting, which has a somewhat expanded explanation of the rationale behind
the proposed fix. This document can be found at:
http://www.gont.com.ar/drafts/TCP-Soft-Errors-Discussion-List.doc .
I'd appreciate any comments on the draft. Thus, I'd be able to address your
comments in the next revision of the draft, and will also sum-up your
feedback and post it to the relevant IETF mailing list (that of the TCPM WG
mailing-list).
BTW, I've set up a page at
http://www.gont.com.ar/drafts/tcp-soft-errors.html so that you have all the
documents available from a single place.

I have verified that Linux behaves in a way compliant to this
proposal. No changes are necessary.

Even 2.0.x kernels behave this way. Others are welcome to
search back even further :-)
